Abstract
1379870 Quinoxaline CHEMICZNA SPOLDZIELNIA PRACY SYNTEZA 25 May 1973 [26 May 1972 8 June 1972] 25233/73 Heading C2C Quinoxaline is produced by reacting at least 11 % by weight of orthophenylenediamine with at least 6% by weight of glyoxal in an aqueous solution in the presence of a salt of an alkali metal and a weak acid. The preferred salt is sodium carbonate. The glyoxal may be used in the form of a solution obtained by the oxidation of acetaldehyde or paraldehyde with nitric acid and which contains up to 30% of other compounds, in particular organic acids.
